(the value 6 is at #957C).
To make Willy run left instead of right, see TECHNICA.TXT of Party
Willy (Special Edition only).

items are free. If n items are free then there are 256-n items in the
game.
The number of free items is at #A3FF in JSW48 (not Softricks, Geoff
Mode, JSW64 or JSW II, and I believe not Erix1 Mode though I have yet
to investigate this properly); JSWED updates this automatically as
you add or delete items.
